✦ Synopsis

Chcmicaf nnd mass-sppcctromctric analysts have estabijshed the presence of sulfur trioxidt in gases sampled from fuel-rich propane-air flames containing r;uIfur. This sulfur triox;de was found to bc independent of the source of sulfur. and its canccntrarian profile correlates welf wirh the cktilattd sdfur monoxide equihbrium profile and is related to the internal surface area of the tip of the uncooled quartz microprobe used to sample the flame gases. It is suggested that interactions bctwecn hydroxyI radicals and suMur monoxide at the quartz microprobe may be the source of the sulfur trioxide.
